Skeletal + Integumentary

Skeletal + Integumentary

The integumentary system is basically the skin. the skin has many functions: -to maintain homeostasis. -to maintain borders. -to protect internal organs among a few more different functions. the skin like all the systems is incredibly important for many issues.

The skeletal system is more about protection, support, red blood cell making, and storage:

-protection-

~the skeletal system protects by covering important organs with bone to anchor and protect from collision/

-support-

~this system supports the weight of the body in the vertebral column. the vertebral column consists of cervical, thoracic and lumbar vertebrae. all of them support the weight of the body.

-storage and cell making-

~ the bones have yellow (in adults) and red (in children) marrow. yellow is for storage because is mostly fat. Red is designed for production of red blood cells.

The skeletal and integumentary system have something in common. both protect internal tissue. the skin and skeleton protect the skeleton is hard like reinforced concrete and the skin absorbs the impacts, maintains boundaries to maintain its physiology going. this is all about homeostasis.

Skin, The anatomy

The Skin

     The purpose of the skin is to protect and maintain boundaries. It keeps the parts below it safe. it keeps water in the body. The skin consists of three main layers. The Epidermis: the top later of the skin. The Dermis (the layer below the epidermis). and the Hypodermis.

The Epidermis:

The Epidermis consists of the outer skin, it is keratinized stratified squamous epithelium. it has sweat pores and hair. in other cases such as the skin in palms and feet the epidermis only has sweat pores and without hair.

The Dermis:

The Dermis is the second layer of the skin, this one much more complex than the epidermis. inside the dermis you find connective tissue, it has macrophages, fibroblasts. within, you find elastic and reticular fibers that give it the elasticity and strength it has. in here is where you find capillaries. and in the gelatinous fibers you can find collagen.

The Hypodermis:

The Hypodermis is the deepest layer of the skin. In this part of the skin is where fat cells reside. it is composed of adipose tissue. The fat in this part of the body help to absorb shock to protect the underlying organs

Silk Tissue??

Tissues made of silk?

     In the TED talk, Flo Omenetto, gives a speech about silk. his speech was about making all kinds of things with silk, among these things he says that it is possible to make things such as tissues, bones for instance since its very useful for protection. he also talks about making cups, microscopic needles, and others as micro electronics, tools, such as bolts and nuts that work underwater etc. all this is very important for science because it can help in many issues like implanting tissues without immune response.

The silk has many purposes to help. mainly the thing that is more important is bone making, if it is possible to make them it could help many people in the world that need tissue. getting it from silk is much better, it would help all kinds of fractures and more serious injuries.
